The Truth About Fuel Additives
NaTasha Brand • August 25, 2025
Miracle in a Bottle or Highway Robbery?
You’re standing in the auto parts aisle, staring at a dizzying array of potions and elixirs that promise to clean your engine, boost your MPG, and restore lost horsepower. In the scorching San Angelo heat, where dust and heat work overtime to gunk up your engine, the promise of a quick fix is tempting. But do these fuel additives actually work, or are you just pouring money into your gas tank?
At Ric Henry’s Auto Service, we’ve seen the good, the bad, and the ugly when it comes to these bottled solutions. Let’s pop the hood and separate the fact from the fiction.
What Are Fuel Additives, Anyway?
In short, they are chemical compounds designed to be added to your fuel to alter its properties. They’ve been around since the dawn of the internal combustion engine. The key is understanding that not all additives are created equal. They generally fall into a few categories:
• Fuel Injector Cleaners: The most common type. They contain detergents meant to dissolve carbon deposits on injectors, intake valves, and combustion chambers.
• Octane Boosters: Claim to increase the fuel’s octane rating, which can help prevent knocking in high-performance engines (but do very little for your average sedan).
• Fuel Stabilizers: Designed to prevent fuel from degrading over time, crucial for lawn equipment or vehicles that sit for months.
• Water Removers (Drying Agents): Aim to absorb small amounts of water contamination in your gas tank, a rare but potential issue.
The Good: When Additives Actually Work
Let’s be fair, some additives have their place. Top-Tier gasoline, which is sold at most major brand stations, already contains a robust package of detergents that meet a higher standard for keeping your engine clean. For the average driver using quality gas, an additive is often redundant.
However, there are scenarios where a good quality cleaner can be beneficial:
• High-Mileage Vehicles: Engines with 75,000+ miles may have significant carbon buildup that standard fuel can’t handle.
• Performance Issues: If you’re noticing a slight rough idle or a small drop in fuel economy, a cleaner might help.
• Preventative Maintenance: Used sparingly (e.g., once every 10,000 miles), they can help prevent major deposits from forming.
The Bad & The Ugly: The Truth About “Magic in a Bottle”
This is where we get to the heart of the matter. For every legitimate product, there are a dozen making outrageous claims.
• The MPG Myth: Be highly skeptical of any product promising dramatic fuel economy gains. Physics and your car’s engineering are the main factors in MPG, not a $20 bottle.
• The “Restore Power” Fantasy: If your engine has lost significant power due to mechanical wear (like worn piston rings or a failing catalytic converter), no additive will bring it back. That requires physical repair.
• The Risk of Damage: Some cheap, aggressive additives can dislodge large chunks of carbon all at once, which can then clog catalytic converters or fuel filters, leading to very expensive repairs.
The San Angelo Angle: Heat, Dust, and Your Engine
Our local conditions are tough on cars. Extreme heat can cause fuel to vaporize differently and make engines more prone to knocking. Our dust can find its way into places it shouldn’t. While a quality additive might help with specific cleaning tasks, it’s no substitute for the real preventative maintenance we specialize in at Ric Henry’s: regular air filter changes, fuel system services, and using the right quality fluids for our climate.
Why Professional Service Beats a Bottle Every Time
Think of it this way: a fuel additive is like using mouthwash. It can provide a fresh feeling, but it’s no substitute for a professional cleaning by a dentist.
At Ric Henry’s Auto Service, when you come to us with a rough idle or loss of power, we don’t guess. We:
1. Hook up advanced diagnostics to read real-time data from your engine.
2. Perform a fuel system cleaning using professional-grade equipment that directly cleans the injectors and intake, far more effectively than any pour-in solution.
3. Back all our work with a 3-year/36,000-mile warranty, something no bottle of additive can offer.
We fix the root cause, not just mask symptoms.
So, do fuel additives work? The answer is: sometimes, for specific, minor issues. They are a Band-Aid, not a cure. For a lasting solution and real peace of mind, trust the professionals who know your car inside and out.
Save your money on magical potions and invest in proven care.

Here in San Angelo, our vehicles face it all: the dust of West Texas backroads, the blazing heat on Chadbourne Street, and the occasional surprise chill. Through it all, we trust our engines to get us to the Concho River or out to the lakes without a second thought. But deep within that trusted powerplant, a critical component might be slowly elongating, turning into a literal ticking time bomb. Let's talk about timing chain stretch, the silent engine killer. The Conductor of the Internal Combustion Orchestra First, what is this thing? Your timing chain (or belt, in some cars) is the mini maestro of your engine. It’s the critical link that synchronizes the rotation of the crankshaft (the part that goes up and down with the pistons) and the camshaft (the part that opens and closes the valves). This precise coordination ensures that fuel and air enter, combust, and exit at the exact right millisecond. When the timing is perfect, your engine purrs with efficiency and power. When it’s off, even slightly, the performance symphony descends into cacophony. The Slow Stretch: Causes & Symptoms Unlike a snapped timing belt which often causes catastrophic failure, a stretching chain is a master of deception. It doesn’t happen overnight. The primary culprits are: • Mileage & Wear : Simply put, everything has a service life. Over thousands of miles and millions of cycles, the chain's pins and bushings wear down. • Poor Lubrication : This is the big one. Old, sludgy oil or infrequent oil changes are public enemy #1 for your timing chain. The chain relies on a constant bath of clean engine oil for lubrication and cooling. In our Texas heat, oil can break down faster. Skipping an oil change isn't just about the oil itself; it's starving this vital component. • Faulty Tensioners : The chain tensioner’s job is to take up slack. When it fails, it allows excess movement, accelerating wear and stretch. So, how do you know your maestro is losing the beat? Listen and feel: • The Tell-Tale Rattle : A persistent rattling or clattering noise from the front of the engine, especially at startup or at low RPMs, is the classic harbinger. • Check Engine Light : The engine’s computer is precise. As timing drifts, it will often trigger codes related to cam/crank correlation. • Performance Woes : Sluggish acceleration, poor fuel economy, rough idling, or even misfires. The engine is literally out of sync. Why This Isn't a DIY Project for Your San Angelo Garage We get it. The DIY spirit is strong. But timing chain replacement is a deep-engine surgery. It requires: • Specialized tools (cam lock bars, crank holders) to lock the engine in time. • Meticulous disassembly, often involving the front of the engine. • Absolute precision in reassembly. Being one tooth off can lead to bent valves, damaged pistons, and an engine that won’t run, turning a repair into a replacement. This is a job where "close" isn't good enough. It requires the expertise and equipment of a seasoned professional.
